Burke, first identified by Us Weekly, was seemingly with Disick during his vacation in Mexico earlier this month. While she didn't share any snapshots with the Keeping Up With the Kardashians star, the model posted a handful of Instagrams with her bikini-clad friends.

"He's back in a really dark place," we were told about his time spent clubbing and pooling at Joe Francis' vacation home. "He was on the road to recovery, bought the new house near Kourtney, and was cordial with her, but he's been up to his old tricks the past couple of weeks."

This isn't the first gal Disick has been spotted out with since splitting with Kardashian last July after 10 years of dating.

Still, the father of three -- Mason, 6, Penelope, 3, and Reign, 1 -- has reunited with Kardashian a number of times as well, including during a family dinner for her late father's 72nd birthday -- which she called a "blessed and magical night" -- and a flirtatious outing to a Kanye West club appearance.

"They were being very flirtatious -- definitely did not look like they had bad blood," a source said about the night spent at 1OAK in L.A., noting they looked "very coupley." Another source said, "The two were super friendly and sitting close all night, certainly not looking like exes."

Kardashian denied rumors the two had rekindled their romance earlier this year, saying, "I feel like every day is different, but we're totally getting along. Like we have three beautiful kids together...He's family. He'll always be."

Meanwhile, Disick recently praised his ex for her NSFW Instagram photo. Check out what he had to say in the below video.
